Abstract
A technique for managing failover from a first data storage system to a second data storage system includes configuring replication settings for data objects associated with VSPs (Virtualized Storage Processors) on a per-VSP basis, such that all of the data objects associated with each VSP share common replication settings. As the first data storage system operates a VSP, operations replicate data written to any of the data objects of the VSP to the second data storage system such that the second data storage system acquires and stores a replica of the VSP. In the event of a failure at the first data storage system, operations fail over the entire VSP, including all of its data objects, to the second data storage system, to restore host access to the data objects from the VSP replicas. A metro-cluster may be formed from multiple data storage systems that use this failover approach.
